In enzymology, aspartate-prephenate aminotransferase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are L-arogenic acid (shown in its carboxylate form) and oxaloacetic acid. Its products are prephenic acid and L-aspartic acid.
This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-arogenate:oxaloacetate aminotransferase. Other names in common use include prephenate transaminase (ambiguous), PAT (ambiguous), prephenate aspartate aminotransferase, and L-aspartate:prephenate aminotransferase.
